Ashburton District Council is in discussions with Ashburton Meat Processors (AMP) about the possibility of a tradewaste discharge from the company’s Bridge Street site.
AMP approached council earlier this year about the option and extended modelling has shown the discharge can be managed in the network and at the wastewater treatment plant.
AMP currently discharges to land and the move to pipe is seen as having significant environmental benefits to the northeast area of Ashburton.
Further discussions will take place on the physical means needed to provide a discharge and a pumping main being built from AMP to the head of the relief sewer near the intersection of Bridge and Kitchener streets.
The discharge option has been looked at in the past but the quality of the discharge has since increased and there is also now more capacity after the upgrade of the Ashburton relief sewer system.
Council assets manager Andrew Guthrie told councillors at a recent briefing that an agreement with AMP had not yet been reached.
If agreed, it would represent a “significant” single point discharge and a likely 10 per cent increase into the system. The discharge would use some of the scheme’s capacity that is allocated for growth, but that would be offset through payment development contributions from AMP, he said.
